ELECTRIC LAMP.

Application filed March 30, 1922. Serial No. 548,158. I

To all whom it may concern:

Be it known that I, WILLIAM H. SPENCER. a citizen of the United States, residing in the city, county, and State of New York. have invented certain new and useful Improvements in Electric Lamps, of which the following is a specification. i

My invention relates to that class of lamps known as reading lamps or piano lamps in which an electric stand is surmounted by a shade securely attached to the stand and generally ca aable of being adjusted both vertically and angularly so as to throw the light in the desired direction.

In the drawings Figure 1 is a view partly in section and partly in elevation of a lamp embodying my invention.

Figure 2 is a plan of the same with the shade removed, indicated by dotted lines.

Figure 3 is a vertical transverse section thru the center of the shade.

Figure 4 is a detail showing more specifically a feature of the invention.

Figure 5 shows the manner in which the end terminals are attached.

Figure 6 shows a modification of my invention in front View and partly in section.

Figure 7 is a transverse section on the line 7-7, Fig. 6 of the same.

Figure 8 is a plan, and

Figure 9 is a detail showing the wiring.

The primary object of my invention is to provide a means for bracing and holding the free end of a shade so that in handling the lamp the shade will not be distorted or pulled off. The invention also has other novel features referred to below.

In the drawing, 1 is any suit-able lamp stand with a base 2. vertical adjustment 3, lamp frame at, and lamp shade 5. The frame 4: consists of a longitudinal bar which surmounts the lamp stand 1 and projects in opposite directions therefrom. In the embodiment shown in Figures 1 to 4: inclusive, the bar 4 comprises angularly arranged legs 16 and 17 which form a longitudinal channel 18 within which is disposed the electric wires 19, 19, connected to lamp sockets 6, 6, provided with terminals 7, 7. One or both of said terminals may be made yieldable to permit the introduction and removal of a line filament lamp 20. Arranged above the lamp 20. is a shade having one edge slidably engaging the horizontal leg 16 of the angle bar, said leg beingdrawnpup into 11 so that while it may turn freely in the I nut it cannot come out. The wires coming up thru the hollow stand are extended along in the of the frame 4L and at their ends are brought up and secured to their terminals 7 They are concealed within the V- shaped channel the adjacent edge of the shade 21 and shielded from theheat of the lamp by means i of leg 17 of the angle bar; Neverthelesssaid wires are entirely accessible and open to view until the shade isplaced in position. The shade is held securely between the lip 8 of the triangular frame and lip 10 of the outerendof the arm 9 so thateven if the entire fixturebe lifted by means of'the shade, it will not be unduly distorted. To remove the shade it is only necessary to turn the swivelled nut 11 into the dotted position shown in Figure 3 when the hook 11 will take the corresponding dotted position and the shade may be lifted free. In Figures 6 and 7, I shoW. a modification of the frame, by means of of my invention in which the shade is made i double, there being provided opposite the arm 9, an arm 13 which is screwed into the head of the frame and remains fixed. This arm 13 has a hook vat the outer end, the same as arm 9, and the shadeis intended to be =clamped between these two hooks by the drawing up of the swivelled nut 11. The lamp frame or holder 14; in this case, is made double sided like a channel bar, open at the upper side to form a trough in which the wires are laid, as shown more clearly in Figures 8 and 9. In this embodiment of my invention, the channel bar 14 surmounts the hollow standard or section 22 and in a vertical plane substantially including the axis of the lamp stand. Said bar is provided at opposite ends with lips 15, 15, for engaging the lamp shade. Figme 8 shows the manner in which the shade is thus supported by lips or hooks at four points in a. very rigid way and also how one support being made adjustable the shade may be easily removed. According to Figures 1, 2 and 8, the hook 8 extends substantially throughout the length of angle bar f and thus imparts stability to the lamp shade when the arm 9 is tightened. It will be seen that when the shade is removed the wires and terminals are all readily accessible.

7 I claim 1. In an electric light support, the combination with a frame comprising longitudinally extending portions angularly arrangedwith respect to each other in transverse cross' sect-ion, a lamp socket, mounted on one of said portions, a lamp shade hav ing one edge slidably mounted on the other of said portions into and out of engagemei'it with a hook, and an endwise adjustable arm provided with a hook movable into and out of position to engage the other edge of said lamp shade. V 2. In an electric light support, the combination with a frame comprising longitudinally extending portions angularly ranged with respect to each other in trans verse cross section, a lamp socket, mounted on one of said portions, a lamp shade having one edge slidably mounted on the other of said portions and movable into and out of engagement with a hook, and an endwise adjustable arm provided with a hook movable into and out of position to engage the other edge of said lamp shade, said frame portions forming a channel for wires between said lamp socket and the adjacent edge of said lamp shade.

3. An electric light support comprising an angle bar having one leg thereof mount ed upon a suitable support and the other leg arranged to carry lamp socket, a lamp shade having interlocking engagement with the first mentioned leg of said angle bar, and a supporting arm adjustably connected to said angle bar and releasably engaging the other edge of said lamp shade.

i. In an electric light, the combination with a stand, of an angle bar comprising a leg mounted on said stand, and another leg diverging therefrom, lamp sockets mounted at opposite ends of the second mentioned leg, a lamp shade having its rear edge in interlocking engagement with the rear edge of the first mentioned leg and forming with the other leg a channel for accommodating the wires leading to said sockets, and a forwardly presented arm connected to said angle bar and releasably interlocking with the forward edge of said lamp shade.

5. In an electric light, the combination with a stand, of an angle bar comprising a leg mounted on said stand, and another leg diverging therefrom, lamp sockets mounted at opposite ends of the second mentioned leg, a lamp shade having its rear edge in interlocking engagement with the rear edge of the first mentioned leg and forming with the other leg a channel for accommodating the wires leading to said sockets, and a forward- 1y presented arm connected to said angle bar and releasably interlocking with the forward edge of said lamp shade, said arm being pro vided on its rear end with a swivelled nut threaded into said stand and on its forward end with a hook for engaging said lamp shade.

6. In an electric light, the combination with a hollow stand, of a bar Sui-mounting said hollow stand and projecting in opposite directions therefrom, said bar being pro vided with a longitudinal channel extending from one end thereof to the other and with a communicating opening between the hollow interior of said stand and said longitudinal channel in said bar, lamp sockets mounted on opposite ends of said bar, electric light wires extending through said stand and chan nel and respectively connected to said sockets, a line filament lamp mounted in said sockets, a shade for said lamp having one edge there of movable laterally into and out of inter locking engagement with a hook carried by said. bar and an arm projecting oppositely to said hook and provided with a hook for interlocking with the opposite edge of said shade, said arm having a swivelled connection with said channelled bar which connection is adjustable endwise towards and away from said bar to clamp and release said shade.
